To make sure LFS boots properly firstly start Debian and as root do
update-grub. That process should pick up LFS (assuming the LFS kernel
installation is completed). If running update-grub doesn't pick up LFS
you might need to install a package in Debian called os-prober.
I haven't tried installing grub from LFS yet.
